Topic: SD card choices (Read 1520 times)

Has anyone bought a fake (wrong class label) SD card? I have a 8GB class 4 SanDisk card and 16GB class 4 SanDisk Ultra that i think is fake. Whenever i try to record with my 550D, it would say "Video Recording Has Been Stopped Automatically" which i think it's normal because it's a fake SD card but when i put it in my Sony TX10 and it would record without any problem. What's the reason behind this? Is it because DSLR is more picky?

I used a software call AJA System Test to test all my SD cards and here is the result.

Blue Class 2 2GB (SanDisk) Write: 4.4, Read: 16.5 (My 550D would record around 12 mins of 1080p until it stops because it's full)Blue Class 4 8GB (SanDisk): Write: 3.2, Read: 15.6 (My 550D would say "Video Recording Has Been Stopped Automatically"Black Class 4 8GB (Sony): Write: 6.8, Read: 17.9 (My 550D would record around 12 mins of 1080p and stops)Grey Class 4 16GB (SanDisk Ultra): Write: 3.3, Read: 14.8 (My 550D would try to record but there would be a bar on the left hand top corner (i think it's buffering) then it would say "Video Recording Has Been Stopped Automatically". It would record 13 seconds of video.
